BionX E-Bike Battery Replacement

AS OF AUGUST 2020, WE ARE NO LONGER REBUILDING BIONX BATTERIES DUE TO A HIGH NUMBER OF FAILURES OF THEIR BATTERY MANAGEMENT SYSTEM BOARDS WHICH WE CANNOT REPLACE. WE RECOMMEND CONTACTING OHM CYCLES OR BIONX LEGACY SHOP.

Do you have a BionX e-bike that needs a new battery? Let us rebuild, refurbish, and upgrade your old one! We can swap in fresh, grade A lithium ion cells to get you back on your wheels. We've squeezed in as much as 40V 13Ah in a rear rack case more than doubling the range of the original battery. We can take care of all form factors of BionX e-bike batteries whether it's the rear rack or down tube style.

Some of these larger downtube, triangular, fin-shaped batteries can hold up to 60 cells, giving them plenty of room to be upgraded to 36V 21Ah.

All of our batteries are warrantied for a full 12 months. All you need to do is fill out our Battery Intake Form and send us the battery, charger, and bike. We'll even recycle your old batteries for you! Don't let a drained battery keep your bike just collecting dust. Give us a call and it'll be going better than new!

BionX E-bike Battery Repair and Upgrade

Due to the nature of the BionX systems, we require the bike in order to validate the rebuild.

    Hi. I’m interested in having my 48v BionX battery rebuilt. I’m serving in the military overseas. I believe I can ship it by air if the battery is installed in the bicycle. I’d basically be mailing you the entire bicycle in order for you to rebuild the battery and then have you mail the entire bicycle and battery back. Has anyone else done this or have you only done local BionX rebuilds? Also. What would be the cost of a rebuild on a 48v D500 bike?

    @Judy We’ve had some luck doing remote jobs and have a 36V BionX system in house for test purposes.

    Not sending trike 1,000 miles to get a battery. Any other options?


  • EBike Marketplace

    @Mike, send in your BionX battery and we’ll check it out for you.

    I have a bionix battery pack which needs be awakened.
    It beeped over winter but was not charged in time.
